Abstract

An electrical machine with a rotor attached to a shaft and a multi-part stator having a yoke ring and stator fins that delimit winding grooves, which accommodate windings or winding segments wound around insulator elements. The stator has a number of first wound insulator elements that are wound one after another with the same first winding wire and a number of second insulator elements that are wound one after another with the same second winding wire.
